IMPROVEMENT IN BOXES EOE STREET STOP-COURS.

TO WHOM IT MAY-CONCERN.: V v

Be it known that we, HARVEY A. Moonn, E. Orts FRINK, `and SAMUEL C. FRINK, of Indianapolis, in the eounty'of Marion, and 'State of Indiana, have made new and useful Improvementsin Street Stop-Cock Boxes for water, gas, and other purposes; and we do hereby declare the following to bea Inll and exact description of the same, reference being had to the drawings that accompany and form a part of these specifications.

The object of cui` invention is to provide a street stop-cock box for the protection of gas and watenpipes, and for obtaining access to them at certain points.

Figure 1, perspective view. I i

Figure 2, sectional view, showing a flange on the inside and one on theoutside.

Figure 3, under side of the cover, showing lugs by which the cover is fastened tothe box.

Letter A, box; letter E, cover. We malte the box cylindrical in form, with a wide flange extending around the top, as may be seenl in fig. 2, at e, to keep it from sinking below the surface; also, a llange runningperpen. dicular with the box,'(see figs. 1 or 2,) ntf, to keep it from turning around whenthe cover is put error removed. On the inside of the box, at the top, for the purpose ofgholding the cover, we make circular inclined anges, shown at la, fig. 2, so that the further we 'turn the cover in one direction, the closer it is held. A At one endof these flanges we place stops z', to prevent the lugs 7:: being carried too far or past the flanges by any means. The cover Bis madeto extend tothe outside of the flange e,havin'g on its upper side a broad lng, L, in the centre, by which it is operated. The cover is depressed or hollowed ir. the centre, so tbc top of the lug L comes on a level with the general surface. On the under side are lugs 7c, to operate en the inclined flanges t, and secure it to thebox.

By the construction of the inclined anges t, it will be readily seon'that the cover can nlwaysbeheld tight, as the ilanges or lugs become worn by use; Simply turning the cover alittle further brings them to a bearing.4

Most of the boxes non in use are so constructed that children and others so disposed can `easily remove the cover, and carry it off, or ll the box with stones or dirt, so that when required for use, in case of lire, or other# wise, thatis, to get to the stop-cock in the pipe, it has to be cleaned out, or taken out entire, which causesa great amount et" trouble and delay. l Y

What we' claim, and desire to secure by Letters Patent, is- A street stop-'cock box for gas, water, or other purposes, provided with the flanges e andf, and the inclined flanges t, substantially as and for the purpose specified. i

Also, the cover, provided with the lugs L and Fc, substantially as'deseribed and for the purposes set forth.
